“Sometimes she will climb into my bag, but she did not and she was not stuck in the lining of my coat or anything like that. I couldn’t find her anywhere,” Melissa said.

WBZ-TV’s Karen Anderson reports.

“There’s a small chance that maybe she was left at Park Street and I was just feeling my scarf. But I’m very positive that I lost her in, I think they said car three, between Park Street and Andrew, because I was getting off at Andrew when I realized didn’t have her.”

she is a very mellow snake- never hisses or bites and is very timid. she is a bit under 3 feet long with a brownish, almost pinkish paisley looking pattern on her back. she is 3 years old and ive had her since she was 5 days old. if you see her, if you find her- please call me

Penelope can get into “really, really small spaces,” according to Melissa.

The train was delayed at the JFK-UMass stop for 15 minutes as people searched the car for the snake. It was not found and the train left.
